    Various sized cuts of 1 ⁄ 2 in (13 mm) drywall with tools for maintenance and installation . Drywall (also called plasterboard, dry lining, [1] wallboard, sheet rock, gib board, gypsum board, buster board, turtles board, slap board, custard board, gypsum panel and gyprock) is a panel made of calcium sulfate dihydrate (), with or without additives, typically extruded between thick sheets of ...

  4. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    A tankless water heater only heats water on demand, so idle water in the piping starts at room temperature. Thus, there may be a more apparent "flow delay" for hot water to reach a distant faucet (in non-point-of-use systems). Many models sold in the UK have introduced a small heat store within the combination boiler to address this issue.

    In traditional plumbing in the UK, the space-heating boiler is set up to heat a separate hot water cylinder or water heater for potable hot water. Such water heaters are often fitted with an auxiliary electrical immersion heater for use if the boiler is out of action for a time. Heat from the space-heating boiler is transferred to the water ...

    Thermal shock resistance measures can be used for material selection in applications subject to rapid temperature changes. The maximum temperature jump, , sustainable by a material can be defined for strength-controlled models by: [4] [3] = where is the failure stress (which can be yield or fracture stress), is the coefficient of thermal expansion, is the Young's modulus, and is a constant ...

    An aquarium heater is a device used in the fishkeeping hobby to warm the temperature of water in aquariums. [1] Most tropical freshwater and marine aquariums are maintained at temperatures that range from 22 to 30 °C (72 to 86 °F). [1] [2] [3] The types include glass immersion heaters and undergravel heating. There are also heating mats that ...

  9. Immersion cooling - Wikipedia

    en.wikipedia.org/wiki/Immersion_cooling

    Single-phase immersion uses a circulation method for the dielectric liquid across hot electronic components and to a heat exchanging approach. A single-phase fluid does not boil or undergo a phase change at any time during the cooling process. Two-phase immersion leverages the heat-absorbing phase change from liquid to gas. [3]
